Among patients undergoing PCI, pretreatment
with a clopidogrel loading
dose was associated with a nonsignificant
18.5% relative reduction in the
combined end point of death, MI, or urgent
target vessel revascularization at
28 days (6.8% pretreatment vs 8.3% no
pretreatment; 95% CI, −14.2% to 41.8%;
P=.23) (FIGURE 2A). For each component
of the combined end point there
were fewer events in patients receiving
clopidogrel pretreatment (pretreatment
vs no pretreatment: death, 0 vs 4;
MI, 52 vs 60; urgent target vessel revascularization,
9 vs 12; total, 61 vs 76).
